Climbing rose plant named ‘Poulcy028’

ABSTRACT

A new garden rose plant of the Climbing class which has abundant, yellow flowers and attractive foliage. This new and distinct variety has shown to be uniform and stable in the resulting generations from asexual propagation.

Botanical designation: Rosa hybrid.

Variety denomination: ‘Poulcy028’.

SUMMARY OF THE INVENTION

The present invention constitutes a new and distinct variety of gardenrose plant of the Climbing rose class, specifically for compactflowering columns, which originated from a controlled crossing betweenthe female seed parent, an unnamed seedling, and the male pollen parent,also an unnamed seedling.

The two parents were crossed during the summer of 2003 and the resultingseeds were planted in a controlled environment in Fredensborg, Denmark.The new variety, named ‘Poulcy028’, originated as a single seedling fromthe stated cross.

The new variety may be distinguished from its male pollen parent andfemale seed parent by the following characteristics. The female seedparent has orange blend flowers, while the new variety has yellowflowers. The male pollen parent is a ground cover rose, while the newplant is a climbing rose.

The objective of the hybridization of this rose variety was to create anew and distinct variety for garden use with unique qualities, such as:

-   -   1. Uniform and abundant yellow flowers;    -   2. Vigorous, but compact growth when propagated both as a budded        rose and on its own roots;    -   3. Exceptional disease resistance; and    -   4. Consistent flowers from the top of the plant to the lower        branches.

This combination of qualities is not present in previously availablecommercial cultivars of this type, known to the inventor, anddistinguish ‘Poulcy028’ from all other varieties of which we are aware.

As part of the rose development program, Mogens N. Olesen germinated theseeds from the aforementioned hybridization during winter of 2003 andconducted evaluations on the resulting seedlings in a controlledenvironment in Fredensborg, Denmark. ‘Poulcy028’ was selected in thespring of 2004 by the inventor as a single plant from the progeny of theaforementioned hybridization.

Asexual reproduction of ‘Poulcy028’ by traditional budding and rootedcuttings was first done by Mogens N. Olesen in the nursery inFredensborg, Denmark in July, 2004. This initial and other subsequentasexual propagations conducted in controlled environments havedemonstrated that the characteristics of ‘Poulcy028’ are true to typeand are transmitted from one generation to the next.

DESCRIPTION OF THE DRAWING

The accompanying color illustrations show as true as is reasonablypossible to obtain in color photographs of this type, the typicalcharacteristics of the buds, flowers, leaves, and stems, of ‘Poulcy028’.

Specifically illustrated in FIG. 1 are stems, leaves, open flowers, withpetals and petals detached, flower buds, and detached sepals showing thereceptacle.

FIG. 2 shows a flowering branch. Plants shown are 2 years of age.

DETAILED DESCRIPTION OF THE VARIETY

The following is a description of ‘Poulcy028’, as observed in its growthin in a field nursery in Marion County, Oreg. Observed plants are 2years of age, and were grown on their own roots. Color references aremade using The Royal Horticultural Society (London, England) ColourChart, 2001, except where common terms of color are used.

For a comparison, several physical characteristics of the rose variety‘Poulyc003’, U.S. Plant Pat. No. 15,106 are compared to ‘Poulcy028’ inChart 1.
